cc8a853c2d perf/x86/uncore: Correct the number of CHAs on EMR
commit 6f7f984fa8 upstream.

Starting from SPR, the basic uncore PMON information is retrieved from
the discovery table (resides in an MMIO space populated by BIOS). It is
called the discovery method. The existing value of the type->num_boxes
is from the discovery table.

On some SPR variants, there is a firmware bug that makes the value from the
discovery table incorrect. We use the value from the
SPR_MSR_UNC_CBO_CONFIG MSR to replace the one from the discovery table:

   38776cc45e ("perf/x86/uncore: Correct the number of CHAs on SPR")

Unfortunately, the SPR_MSR_UNC_CBO_CONFIG isn't available for the EMR
XCC (Always returns 0), but the above firmware bug doesn't impact the
EMR XCC.

Don't let the value from the MSR replace the existing value from the
discovery table.

e1eb041912 x86/sgx: Break up long non-preemptible delays in sgx_vepc_release()
commit 3d7d72a34e upstream.

On large enclaves we hit the softlockup warning with following call trace:

	xa_erase()
	sgx_vepc_release()
	__fput()
	task_work_run()
	do_exit()

The latency issue is similar to the one fixed in:

  8795359e35 ("x86/sgx: Silence softlockup detection when releasing large enclaves")

The test system has 64GB of enclave memory, and all is assigned to a single VM.
Release of 'vepc' takes a longer time and causes long latencies, which triggers
the softlockup warning.

Add cond_resched() to give other tasks a chance to run and reduce
latencies, which also avoids the softlockup detector.

f9a3d6f037 s390/ipl: add missing secure/has_secure file to ipl type 'unknown'
commit ea5717cb13 upstream.

OS installers are relying on /sys/firmware/ipl/has_secure to be
present on machines supporting secure boot. This file is present
for all IPL types, but not the unknown type, which prevents a secure
installation when an LPAR is booted in HMC via FTP(s), because
this is an unknown IPL type in linux. While at it, also add the secure
file.

8bf567b63c arm64: sdei: abort running SDEI handlers during crash
commit 5cd474e573 upstream.

Interrupts are blocked in SDEI context, per the SDEI spec: "The client
interrupts cannot preempt the event handler." If we crashed in the SDEI
handler-running context (as with ACPI's AGDI) then we need to clean up the
SDEI state before proceeding to the crash kernel so that the crash kernel
can have working interrupts.

Track the active SDEI handler per-cpu so that we can COMPLETE_AND_RESUME
the handler, discarding the interrupted context.

e6e6a5f50f x86/MCE: Always save CS register on AMD Zen IF Poison errors
commit 4240e2ebe6 upstream.

The Instruction Fetch (IF) units on current AMD Zen-based systems do not
guarantee a synchronous #MC is delivered for poison consumption errors.
Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, the
microarchitecture does guarantee that the exception is delivered within
the same context. In other words, the exact rIP is not known, but the
context is known to not have changed.

There is no architecturally-defined method to determine this behavior.

The Code Segment (CS) register is always valid on such IF unit poison
errors regardless of the value of MCG_STATUS[EIPV|RIPV].

Add a quirk to save the CS register for poison consumption from the IF
unit banks.

This is needed to properly determine the context of the error.
Otherwise, the severity grading function will assume the context is
IN_KERNEL due to the m->cs value being 0 (the initialized value). This
leads to unnecessary kernel panics on data poison errors due to the
kernel believing the poison consumption occurred in kernel context.

ba50e7773a x86/sev: Make enc_dec_hypercall() accept a size instead of npages
commit ac3f9c9f1b upstream.

enc_dec_hypercall() accepted a page count instead of a size, which
forced its callers to round up. As a result, non-page aligned
vaddrs caused pages to be spuriously marked as decrypted via the
encryption status hypercall, which in turn caused consistent
corruption of pages during live migration. Live migration requires
accurate encryption status information to avoid migrating pages
from the wrong perspective.

commit 9f5ba4b3e1 upstream.

The lscpu command is broken since commit cab56b51ec ("parisc: Fix
device names in /proc/iomem") added the PA pathname to all PA
devices, includig the CPUs.

lscpu parses /proc/cpuinfo and now believes it found different CPU
types since every CPU is listed with an unique identifier (PA
pathname).

Fix this problem by simply dropping the PA pathname when listing the
CPUs in /proc/cpuinfo. There is no need to show the pathname in this
procfs file.

43a57ca7dd um: Fix hostaudio build errors
[ Upstream commit db4bfcba7b ]

Use "select" to ensure that the required kconfig symbols are set
as expected.
Drop HOSTAUDIO since it is now equivalent to UML_SOUND.

Set CONFIG_SOUND=m in ARCH=um defconfig files to maintain the
status quo of the default configs.

Allow SOUND with UML regardless of HAS_IOMEM. Otherwise there is a
kconfig warning for unmet dependencies. (This was not an issue when
SOUND was defined in arch/um/drivers/Kconfig. I have done 50 randconfig
builds and didn't find any issues.)

This fixes build errors when CONFIG_SOUND is not set:

ca5e8427e2 x86/speculation: Mark all Skylake CPUs as vulnerable to GDS
[ Upstream commit c9f4c45c8e ]

The Gather Data Sampling (GDS) vulnerability is common to all Skylake
processors.  However, the "client" Skylakes* are now in this list:

	https://www.intel.com/content/www/us/en/support/articles/000022396/processors.html

which means they are no longer included for new vulnerabilities here:

	https://www.intel.com/content/www/us/en/developer/topic-technology/software-security-guidance/processors-affected-consolidated-product-cpu-model.html

or in other GDS documentation.  Thus, they were not included in the
original GDS mitigation patches.

Mark SKYLAKE and SKYLAKE_L as vulnerable to GDS to match all the
other Skylake CPUs (which include Kaby Lake).  Also group the CPUs
so that the ones that share the exact same vulnerabilities are next
to each other.

Last, move SRBDS to the end of each line.  This makes it clear at a
glance that SKYLAKE_X is unique.  Of the five Skylakes, it is the
only "server" CPU and has a different implementation from the
clients of the "special register" hardware, making it immune to SRBDS.

This makes the diff much harder to read, but the resulting table is
worth it.

I very much appreciate the report from Michael Zhivich about this
issue.  Despite what level of support a hardware vendor is providing,
the kernel very much needs an accurate and up-to-date list of
vulnerable CPUs.  More reports like this are very welcome.

* Client Skylakes are CPUID 406E3/506E3 which is family 6, models
  0x4E and 0x5E, aka INTEL_FAM6_SKYLAKE and INTEL_FAM6_SKYLAKE_L.

f17d5efaaf powerpc/iommu: Fix notifiers being shared by PCI and VIO buses
[ Upstream commit c37b6908f7 ]

fail_iommu_setup() registers the fail_iommu_bus_notifier struct to both
PCI and VIO buses.  struct notifier_block is a linked list node, so this
causes any notifiers later registered to either bus type to also be
registered to the other since they share the same node.

This causes issues in (at least) the vgaarb code, which registers a
notifier for PCI buses.  pci_notify() ends up being called on a vio
device, converted with to_pci_dev() even though it's not a PCI device,
and finally makes a bad access in vga_arbiter_add_pci_device() as
discovered with KASAN:

With JUMP_LABEL=n, hcall_tracepoint_refcount's address is being tested
instead of its value. This results in the tracing slowpath always being

4c8568cf4c powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT
[ Upstream commit eac030b22e ]

lppaca_shared_proc() takes a pointer to the lppaca which is typically
accessed through get_lppaca().  With DEBUG_PREEMPT enabled, this leads
to checking if preemption is enabled, for example:

  BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693
  caller is lparcfg_data+0x408/0x19a0
  CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2
  Call Trace:
    dump_stack_lvl+0x154/0x200 (unreliable)
    check_preemption_disabled+0x214/0x220
    lparcfg_data+0x408/0x19a0
    ...

This isn't actually a problem however, as it does not matter which
lppaca is accessed, the shared proc state will be the same.
vcpudispatch_stats_procfs_init() already works around this by disabling
preemption, but the lparcfg code does not, erroring any time
/proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.

Instead of disabling preemption on the caller side, rework
lppaca_shared_proc() to not take a pointer and instead directly access
the lppaca, bypassing any potential preemption checks.

The ov5640 has depended on these names since the driver was committed

regulator names since its own initial commit in 2020.

Perhaps the regulators were left on in previous 410c bootloaders. In any

[ Upstream commit 44ad820780 ]

Both Luxul's XAP devices (XAP-810 and XAP-1440) are access points that
use a non-default design. They don't include switch but have a single
Ethernet port and BCM54210E PHY connected to the Ethernet controller's
MDIO bus.

Support for those devices regressed due to two changes:

1. Describing MDIO bus with switch
After commit 9fb90ae6ca ("ARM: dts: BCM53573: Describe on-SoC BCM53125
rev 4 switch") Linux stopped probing for MDIO devices.

2. Dropping hardcoded BCM54210E delays
In commit fea7fda7f5 ("net: phy: broadcom: Fix RGMII delays
configuration for BCM54210E") support for other PHY modes was added but
that requires a proper "phy-mode" value in DT.

Both above changes are correct (they don't need to be reverted or
anything) but they need this fix for DT data to be correct and for Linux
to work properly.

d309b170ea x86/mm: Fix PAT bit missing from page protection modify mask
[ Upstream commit 548cb93205 ]

Visible glitches have been observed when running graphics applications on
Linux under Xen hypervisor.  Those observations have been confirmed with
failures from kms_pwrite_crc Intel GPU test that verifies data coherency
of DRM frame buffer objects using hardware CRC checksums calculated by
display controllers, exposed to userspace via debugfs.  Affected
processing paths have then been identified with new IGT test variants that
mmap the objects using different methods and caching modes [1].

When running as a Xen PV guest, Linux uses Xen provided PAT configuration
which is different from its native one.  In particular, Xen specific PTE
encoding of write-combining caching, likely used by graphics applications,
differs from the Linux default one found among statically defined minimal
set of supported modes.  Since Xen defines PTE encoding of the WC mode as
_PAGE_PAT, it no longer belongs to the minimal set, depends on correct
handling of _PAGE_PAT bit, and can be mismatched with write-back caching.

When a user calls mmap() for a DRM buffer object, DRM device specific
.mmap file operation, called from mmap_region(), takes care of setting PTE
encoding bits in a vm_page_prot field of an associated virtual memory area
structure.  Unfortunately, _PAGE_PAT bit is not preserved when the vma's
.vm_flags are then applied to .vm_page_prot via vm_set_page_prot().  Bits
to be preserved are determined with _PAGE_CHG_MASK symbol that doesn't
cover _PAGE_PAT.  As a consequence, WB caching is requested instead of WC
when running under Xen (also, WP is silently changed to WT, and UC
downgraded to UC_MINUS).  When running on bare metal, WC is not affected,
but WP and WT extra modes are unintentionally replaced with WC and UC,
respectively.

WP and WT modes, encoded with _PAGE_PAT bit set, were introduced by commit
281d4078be ("x86: Make page cache mode a real type").  Care was taken
to extend _PAGE_CACHE_MASK symbol with that additional bit, but that
symbol has never been used for identification of bits preserved when
applying page protection flags.  Support for all cache modes under Xen,
including the problematic WC mode, was then introduced by commit
47591df505 ("xen: Support Xen pv-domains using PAT").

The issue needs to be fixed by including _PAGE_PAT bit into a bitmask used
by pgprot_modify() for selecting bits to be preserved.  We can do that
either internally to pgprot_modify() (as initially proposed), or by making
_PAGE_PAT a part of _PAGE_CHG_MASK.  If we go for the latter then, since
_PAGE_PAT is the same as _PAGE_PSE, we need to note that _HPAGE_CHG_MASK
-- a huge pmds' counterpart of _PAGE_CHG_MASK, introduced by commit
c489f1257b ("thp: add pmd_modify"), defined as (_PAGE_CHG_MASK |
_PAGE_PSE) -- will no longer differ from _PAGE_CHG_MASK.  If such
modification of _PAGE_CHG_MASK was irrelevant to its users then one might
wonder why that new _HPAGE_CHG_MASK symbol was introduced instead of
reusing the existing one with that otherwise irrelevant bit (_PAGE_PSE in
that case) added.

Add _PAGE_PAT to _PAGE_CHG_MASK and _PAGE_PAT_LARGE to _HPAGE_CHG_MASK for
symmetry.  Split out common bits from both symbols to a common symbol for
clarity.

800bf8a222 arm64: tegra: Fix HSUART for Smaug
[ Upstream commit 590bfe5183 ]

After commit 71de0a054d ("arm64: tegra: Drop serial clock-names and
reset-names") was applied, the HSUART failed to probe and the following
error is seen:

 serial-tegra 70006300.serial: Couldn't get the reset
 serial-tegra: probe of 70006300.serial failed with error -2

Commit 71de0a054d ("arm64: tegra: Drop serial clock-names and
reset-names") is correct because the "reset-names" property is not
needed for 8250 UARTs. However, the "reset-names" is required for the
HSUART and should have been populated as part of commit a63c0cd837
("arm64: dts: tegra: smaug: Add Bluetooth node") that enabled the HSUART
for the Pixel C. Fix this by populating the "reset-names" property for
the HSUART on the Pixel C.

value of "ranges" needs to be determined yet.

Add missing "detach" mailbox to this board to permit the CPU to inform

firmware to stop IPC communication and to reinitialize the resources for
a re-attach.

Without this mailbox, detach is not possible and kernel log contains the
following warning to, so make sure all the STM32MP15xx platform DTs are
